can be used with the 5V version of this regulator to power a 5 V circuit

QTR-3A Reflectance Sensor Array SF_Irons and Tips low quiescent current (see theThis compact module packs three IR LED phototransistor pairs onto a 1. 25 0. 3 board. The sensors are mounted on a 0. 375 pitch, making this array a great minimal sensing solution for a line following robot. Each sensor provides a separate analog voltage output . The QTR 3A reflectance sensor array requires analog inputs to take readings. The similar QTR 3RC reflectance sensor array is available with digital I O compatible outputs. Functional
